For how long can someone from another country legally drive in the U.S. using their home country’s driver's license?

The correct duration for which someone from another country can legally drive in the U.S. using their home country’s driver's license typically depends on state laws, but a common practice in many states is that a foreign driver's license is valid for driving in the U.S. for up to one year, as long as the individual is a visitor. This allowance is generally in place to accommodate tourists and temporary residents who may not have had the opportunity to obtain a U.S. driver's license.

While it is important for foreign drivers to know the specific regulations in the state they are visiting, the one-year guideline serves as a general standard that has been recognized across many jurisdictions. This duration aligns with the intention of temporary visits, allowing foreign nationals to maintain some degree of normalcy without immediately needing to convert to a U.S. driver's license.

The other options reflect durations that are either too short or do not broadly apply across various jurisdictions. For example, three months and six months might apply in some specific circumstances but do not cover the general allowance provided to international drivers. The choice related to the validity of the visa refers to a separate aspect of legality regarding residency and immigration status, rather than a straightforward response to the question of driving duration based on a foreign license.
